rinetd couldn't bind address

[maged67]

I am trying to setup the rinetd to route the traffic outside the firewall to a certain server inside our netwrok, so for example I input that line in the inetd.conf

192.168.110.5 80 192.168.110.20 80 so any traffic coming from network 110.5 on port 80 will be forwarded to network 110.20 on port 80

but when I start the rinetd I get this error message "couldn't bind to address 192.168.110.5 port 80

any clue?

Thanks
